Benefits of technology
[0020]According to the embodiments of the present invention described above, it is possible to enable a radio communication device to collect information of another radio communication device existing within its radio range.
Problems solved by technology
However, the above-described services such as UPnP and Bonjour can only find the communication device that joins the same network as the communication device on the finding side and is compatible with the same service.
Further, because it is specified for direct data transmission between slave units using the TDLS to perform connection processing between the slave units by using data packets, the master unit is unable to recognize the contents of the connection processing.
Thus, there is a concern that it is difficult for a certain radio communication device to collect information of a radio communication device that exists within its radio range but belongs to a different communication group.

[0032]Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the appended drawings. Note that, in this specification and the appended drawings, structural elements that have substantially the same function and structure are denoted with the same reference numerals, and repeated explanation of these structural elements is omitted.
[0033]In this specification and the drawings, each of a plurality of structural elements having substantially the same function is distinguished by affixing a different number with a hyphen to the same reference numeral in some cases. For example, a plurality of structural elements having substantially the same function are distinguished like a master unit 20-1, a master unit 20-2 and so on where necessary. However, when there is no particular need to distinguish between a plurality of structural elements having the same function, they are denoted by the same reference numeral. For example, when there is no...

Provided is a radio communication device which includes a communication unit that communicates with a connected radio communication device operating as a master unit, and a control unit that, when a prescribed inquiry packet sent from another radio communication device is received by the communication unit, controls the communication unit to send a response packet containing service information indicating a service with which the radio communication device is compatible to said another radio communication device.
Description
BACKGROUND OF THE INVENTION[0001]Field of the Invention[0002]The present invention relates to a radio communication device, a radio communication system, a program, and a radio communication method.[0003]Description of the Related Art[0004]A wireless LAN (Local Area Network) system as represented by IEEE (Institute of Electrical and Electronics Engineers) 802.11 is becoming increasingly common in place of a wired network for its advantages such as high flexibility of equipment. For example, as disclosed in Japanese Unexamined Patent Publication No. 2008-283590, the wireless LAN system standardized by the IEEE 802.11 is composed of groups of radio communication devices which are an access point operating as a master unit and a plurality of stations operating as slave units, and a plurality of stations are connected to one access point.[0005]Further, services such as UPnP and Bonjour are known as application services for finding a communication device that exists on an IP network.
